Aas determination of aluminium levels in tea and other plants grown in the same locality

Abstract

Total concentration of aluminium in leaves, stem, and roots of tea plant from various places was determined and compared to that in other plants grown in the same locality.

Results showed that tea plant accumulated more aluminium than most other plants grown in the same locality with older leaves accumulating most of the aluminium in the range of 1350–2100μg/g. Grains were found to contain very little aluminium and in most cases it was not detectable. Leafy vegetables accumulated significant amounts of aluminium ranging from 200–650μg/g.

Accumulation of aluminium in most plants was in the order of aluminium in leaves > aluminium in the roots > aluminium in stem.
